50 home run club
In Major League Baseball, the 50 Home Run Club is an informal term applied to the group of players who have hit 50 or more home runs in a single season. The 50 Home Run Club was "founded" by Babe Ruth in 1920. At the time, he became the first player to hit not only 50 homeruns in a season, but 40 and 30 as well, breaking his own single season record of 29 from the 1919 season.
Mentioned less frequently are the 60 Home Run Club and the 70 Home Run Club, which have 5 and 2 members respectively. These "clubs" have become more populated since the 1998 season, which saw membership in the 60 Home Run Club double. That year, Mark McGwire became the first member of the 70 Home Run Club when he set a new single-season record. He has since been surpassed by Barry Bonds, the other member of the 70 Home Run Club.
The club
At the start of the 2006 season, there were 22 members of the 50 Home Run Club who have hit 50-or-more homeruns in a single season 37 times:
